second edition Barrett, T. W. (Terence William) 1939- creator text bibliography Electronic books. si Singapore World Scientific 2022 monographic eng 1 online resource (376 p.) : ill. "The aims of the book are: (1) to extend Maxwell theory to non-Abelian group forms; (2) to demonstrate that the foundations of electromagnetism are topological; (3) to show the multi-disciplinary nature of communications; (4) to demonstrate the effectiveness of modulated signals in penetrating media; (5) to demonstrate that geometric (Clifford) algebra is the appropriate algebra describing modulated signals. The book is important in indicating that the classical theory of electromagnetism, or Maxwell theory, can be developed to address situations and signals of differing symmetry form, and that different topological spaces require that development"-- Preface -- Electromagnetic phenomena not explained by Maxwell's equations -- Sagnac effect: a consequence of conservation of action due to gauge field global conformal invariance in a multiply-joined topology of coherent fields -- Topological approaches to electromagnetism -- Orthogonal signal spectrum overlay -- Polarization and axis modulated ultrawideband signal transmission -- Geometric (Clifford) algebra: transmission through disturbed media and transient wave states.
